WARPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 670,135, dated March19, 1901.

Application filed May 26, 1900. Serial No. 18,083. (No model- To allwhom it may concern:

Be it known that I, CHARLES H. KNAPP, a citizen of the United States,residing in Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Warping-Machines;and I do herebydeclare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it'appertains to make and use the same, reference being hadto the accompanying drawings, and to characters of reference markedthereon, which form a part of this specification.

This invention relates to warping or beaming machines; and it hasreference particularly to the mechanism employed in certain machines ofthis nature whereby a traverse motion is effected, so as to produce acontinuous back-and-forth spiral winding of the warp on the beam orspools or bobbins.

The object of the invention is to provide a simple and durabletraverse-motion mechanism, especially for warping-machines, whereby thewinding of the material onto the beam or bobbins may be accomplishedwith the highest degree of celerity, the cops produced being at the sametime uniformly and compactly built up.

Referring to the accompanying drawings, wherein corresponding charactersof reference indicate like parts, Figure 1 is a view in front elevationof the upper portion of a warping-machine provided with mytraverse-motion mechanism. Fig. 2 is an inner end view of saidtraverse-motion mechanism. Fig. 3 is a top plan view, a portion thereofbeing broken away to show the internal construction. Fig. 4 is alongitudinal vertical sectional View of said mechanism. Fig. 5 is asectional view of said mechanism on the line a". a; in Fig. 6. Fig. 6 isa transverse sectional view on the line y y in Fig. 4. Fig. 7illustrates acertain detail of the invention. Fig. 8 is an outer endview of the mechanism, certain parts being removed. Fig. 9 is an outerend view similar to Fig. 8, the parts removed in said figure being inthis figure shown. Fig. 10

shows one of the cops which may be produced by a machine having myimproved traversemotion mechanism. Figs. 11 and 12 are views, slightlyenlarged, of a portion of the traverse-motion mechanism, showingopposite sides of a certain double screw constituting a part thereofFig. 13 is a plan View of a certain bushing also constituting a portionof said traverse-motion mechanism, and Fig.

14 is an enlarged'view of some of the parts 7 cut, filed March 6, 1900,Serial No. 7,483; but

it is to be understood that theinvention may also be used in connectionwith other warpingmachines.

In said drawings, a designates the frame of the machine, in which isjournaled the main drive-shaft 17, carrying at one end a drivingpulley cand at the other end a friction-disk (1. Through the medium of thefriction-disk and a friction-wheel e a vertical shaftf, on which saidfriction-wheel is keyed and which is journaled in a bracket g, isadapted to be rotated. h is another friction-wheel whose purpose issimply to control the position of the friction -wheel e relatively tothe disk through the medium of suitable mechanism, as duly set forth inmy copending application above mentioned. Above the shaft 19 a shaft 71is alsojournaled in the frame, the same protruding beyond, one of theend uprights of said frame extending over the shaftf, to which it isoperatively connected through the medium of intermeshing bevel-gearsjand 7c, carried by said shafts. Back of the shaft i is disposed anothershaft Z, upon which is journaled a series of beams m, each side of andclose to which are disposed gravity-actuated rollers '11, which aresupported in levers 0, that are suitablyfulcrumed upon the frame, asalso set forth in my said application. Only one of the rollers 72 isillustrated in the drawings. Both sides of the shaft 1' are disposedstationary shafts p, which connect the side standards of the frame. Onthese shafts is supported a bracket q, in which is journaled one end ofa shaft 7", having a keyway 3. On the shaft r is secured a series ofcollars t, carryingsecuring-screws 7.6, which engage the keyway in theshaft and prevent the collars from turning. The shaft 0" also carriesbobbins I), which alternate with the collars and which are adapted tobe-driven thereby in the usual manner by means of face-plates w, whichsaid collars carry and which are preferably provided with pins engagingorifices in the heads of the bobbins.

It should be remarked that the beams m correspond in number to thebobbins o. In

other words, what is usually a single beam is divided up into a numberof smaller beams, one for each bobbin, and thus any variations existingin the several warps because the threads thereof are of varyingqualities are accommodated. Ashereinafterexplained,the bobbins have atraverse or longitudinally-reciprocating motion imparted to them as theyrotate, and so the width of each beam m should be at least equal to thedistance between the extreme points to which the corresponding bobbinmoves.

Upon each of the shafts p is adjustably secured, by means of a set-screwz, a bracket 1, and upon the protruding end of the shaft 2' is supportedanother bracket 2. These brackets sustain a casting 3, whosedownwardlyextending projections 4 are secured to the several brackets,preferably by bolts 5. Said casting is in the form of a cylindricalcasing, which is open at the bottom for a portion of the distancebetween the projections 4 and which at its rear end has other openings6, disposed the one above the other. In this casing is disposed alongitudinally-movable and revoluble sleeve 7, having one end closed byan integral head 8, into which projects the squared end 9 of the shaftr, said shaft being thereby supported at this end. The shaft is movablelongitudinally with the sleeve in its bearing in the bracket 2. Theopenings 6 are provided for the accommodation of a gear 10, which thesleeve 7 carries, said sleeve having a keyway 11, in which anantifriction-key consisting of one or more rollers 12, disposed in thebore of the gear, works. The gear 10 is inclosed by a gear-casing 12,which is secured upon the casing 3, over the upper opening 6 therein,preferably by means of screws 13. On the shaft 71 is arranged a pinion14, which meshes with the gear 10, so as to rotate the same.

In a revoluble bushing 15, arranged in the outer end of the casing 3, ismounted a shaft 16, which is provided with reverse screwthreads orspiral grooves 17 for a portion of its length. Upon the outer end ofthis bushing is fixed a pinion 18, upon which is pivoted a latch 19,adapted to lock said pinion and shaft together and consisting of a shortbar, which is adapted to engage notches 20, alternately disposed onopposite sides of the shaft, as seen in Fig. 4, said bar being adaptedto be held in operative position in any one of the notches by athumb-screw 21 on the pinion. By manipulating the latch and moving theshaft lengthwise the latter can be so adj ustecl as to expose more orless of its threaded portion. It should be remarked that the bushing isprovided with a head 22 at its inner end, which not only prevents theoutward movement of said bushing, but whose end (said inner one) insteadof being plain has a shallow recess 23 formed therein. (See Figs. 11 and13.) The function of this recess is the same as that of a recess 24,provided in the adjacent face of an integral head 25 at the other end ofthe screw, and will be again referred to.

The bracket 2 is provided with a curved slot 26, in which is adjustablyarranged a stud 27, which carries a pair of pinions 28 29, the latterbeing the smaller. The pinion 29 meshes with the pinion 18, whereas thepinion 28 meshes with a smaller pinion 30 on the end of the shaft 2'.

Upon the outer end of the sleeve 7 is carried a bracket, which is bestshown in Fig. 6. This bracket consists of two members in the form ofsubstantially semicircular straps 31 32, which together surround thesleeve, being disposed in an annular groove 33 therein. They are heldtogether at their ends by screws 34, said straps, respectively, havingprojections 35 36, affording a bearing between them, in which is looselyarranged a short spindle 37, carrying a lever 38 at one end and a pawl39 at the other end, said pawl being tapered at both its ends and beingadapted to engage the grooves 17 of the shaft 16. The lever 38 isnormally pulled in one direction by a spring 40, which connects saidlever with a pin 41, mounted in the projection 35 of the strap 31. Inorder to prevent the bracket just described from revolving with thesleeve 7, I provide a detent 42, which is secured in place by the screw34 and works in a longitudinal slot 43 in the upper portion of thecasing 33.

In operation, the shaft '5 being rotated from the shaft 1) through theintermediate connecting mechanism described, the pinion 14 will drivethe pinion 10, which in turn will rotate the sleeve 7, and consequentlythe shaft 7' and the several spools or bobbins carried thereby. At thesame time said shaft i will rotate the shaft 16 through the medium ofthe pinions 30, 28, 29, and 18. Since the sleeve 7 is connected with theshaft 16 by the pivoted double pawl 39, which the bracket described asloosely surrounding said sleeve carries, a rapid reciprocating motionwill be imparted in an obvious and well-known manner to the sleeve 7,and consequently to the shaft 0" and the bobbins simultaneously with therotation thereof, this being permitted by virtue of the key connectionafforded between the gear-wheel 10 and the sleeve. It is to be observedthat the reciprocation of the sleeve 7 is the direct result of therotation of the threaded shaft 16, connected with said sleeve, as it is,through the medium of pawl 39 and the non-revoluble bracket which,carrying said pawl, loosely embraces the sleeve and is guided forreciprocation in the slot 43 of the casing. The pawl is reversed, ofcourse, at each of its limits of motion in the threads of the screw bythe recesses 23 and 24.

By virtue of the fact that the traverse motion is imparted to thebobbins and not to the warps, as in the usual manner, I find that I cannot only wind cops on the bobbins more compactly and more uniformly thanis possible in existing machines, but that the compactness anduniformity of the winding is so perfect that bobbins without heads-2'.e., bobbins in the shape of plain cylinders (see Fig. 10)may be used,and thus all the objections attendant upon the use of headed bobbins areobviated.

It will be observed that it is only necessary to shift the shaft 16,adjusting it by means of the latch 19, in order to produce a traversemotion of more or less length, according to the size of the bobbins onthe shaft 1'.

I claim 1. The combination, in a warping or other similar machine, witha frame, of a revoluble bobbin or beam carrying shaft, said shaft bein glongitudinally reciprocatory, a reciprocatory and revoluble sleeveoperatively connected to said shaft at one end thereof, anotherrevoluble shaft, and a non-revoluble bandshaped bracket surrounding saidslee ve and engaging and adapted to reciprocate with the same, said lastnamed shaft and said bracket having a pawl and re verse screwthreadconnection between them, substantially as described.
